Historic partnership between POWER-GEN Asia and the Indonesian Electrical Power Society

1 June 2018: PennWell and MKI (Masyarakat Ketenagalistrikan Indonesia), the Indonesian
Electrical Power Society, are proud to announce a special Cooperation Partnership that sees
POWER-GEN Asia* and the highly-respected National Electricity Day coming together this year to
create an exciting joint power generation event, called The 73rd Indonesia National Electricity Day
– POWER-GEN Asia.

This joint event, taking place at the Indonesia Convention Exhibition in BSD City, Greater Jakarta,
on 18-20 September 2018, provides all attendees with the unique opportunity to meet, engage
and network with power generation professionals from Indonesia, the wider Asian region and
from across the globe – an Asian power-focused event with a genuine international footprint.

For more than a quarter of a century, POWER-GEN Asia has served as a leading forum where the
electric power industry can meet, share and discuss solutions for advancing Asia and particularly
the ASEAN’s electricity future. Attracting over 8,500+ attendees from more than 75 countries,
POWER-GEN Asia covers all forms of power generation, from conventional to renewable energy
and other low-carbon options.

Hari Listrik Nasional or National Electricity Day, organized by MKI on behalf of the Ministry of
Energy and Mineral Resources, and PT. PLN Persero, the state-owned utility, is recognized as the
foremost event for key stakeholders in Indonesia’s power sector, where discussions on how best
to meet the challenges facing the industry and develop opportunities are held. National Electricity
Day also has a central role in supporting the Government’s important electricity-related
objectives.

Dr. Heather Johnstone, Event Director of POWER-GEN Asia, said: “We are extremely honoured to
be cooperating with such a prestigious organization as MKI, especially as this year marks the first
time we have staged POWER-GEN Asia in Indonesia. By combining the strengths of these two
highly-respected shows into The 73rd Indonesia National Electricity Day- POWER-GEN Asia we can
offer attendees, whether from Indonesia or beyond, a truly productive three-day event.“

Dr. Heru Dewanto, Secretary General of MKI, said: “We are delighted to be working with
PennWell because the focus and expertise of POWER-GEN Asia complements National Electricity
Day extremely well. Further, with POWER-GEN Asia being part of the POWER-GEN family, the 73rd
Indonesia National Electricity Day – POWER-GEN Asia will provide a fantastic opportunity to
strengthen global connections within Indonesia, enabling us to further implement the objectives of
the Government”.
